Transport and Storage
Please keep the original packaging for later transport, e.g. for calibration. Any
transport damage due to faulty packaging will be excluded from warranty claims.
In order to avoid instrument damage, it is advised to remove batteries when not
using the instrument over a certain time period. However, should the instrument
be contaminated by leaking battery cells, you are kindly requested to return it to
the factory for cleaning and inspection.
Instruments must be stored in dry and closed areas. In the case of an instrument
being transported in extreme temperatures, a recovery time of minimum 2 hours
is required prior to instrument operation.
Safety
The METERMAN Leakage Clamp AC50 has been manufactured and tested to
comply with the safety regulations for electronic measuring equipment contained
in IEC61010 and EN 61010, and left the factory in a safe condition. To maintain
this condition, the user must observe the safety instructions contained in this
users manual.
To avoid electric shock, safety measures must be observed when working with
voltages higher than 70V d.c. or 33 V r.m.s.(46.7 V peak).
Before each measurement make sure that the test leads and the instrument are
undamaged.
Only handle test leads and probes on the grips provided. Avoid touching probes
under any circumstances.
Measurements in dangerous proximity of electrical installations are only to be
executed when instructed by a responsible electrical specialist, and never alone.
The relevant safety regulations for electrical plant and equipment must be obser-
ved during all operations.
The instrument must only be used in the specified ranges.
Before opening the instrument, it must be disconnected from all circuits.
Protect the instrument from prolonged exposure to direct sunlight.
3
Appropriate Usage
The instrument may only be used under those conditions and for those purposes
for which it was conceived. For this reason, in particular the safety references, the
technical data including environmental conditions and the usage in dry environ-
ments must be followed.
When modifying or changing the instrument, the operational safety is no longer
ensured.
The instrument may only be opened by an authorised service technician, e.g. for
fuse replacement.

Operation
Preparation and safety measures
Installing the battery
Before using the instrument, the battery must be installed. This is carried out as fol-
lows:
1) Separate the instrument from any circuit, and remove the test leads.
2) Open the housing by removing the screw on the rear face.
3) Fit a new battery (type 1.5 V IEC LR6), taking care that the polarity is correct. Ma-
kesure that no wires are trapped between the 2 halves of the housing, and close
itagain
4) The instrument is now ready for use.
• The selector switch must be turned to the desired type of measurement before the
probes are connected to the unit under test (UUT).
• Before switching to a new function, the probes must always be removed from the
UUT.
• Use the instrument only in clean and dry surroundings. Dirt and moisture reduce
the effectiveness of the insulation, with consequent danger of electric shock,
especially when dealing with high voltages.
Use the instrument only in the specified ranges. Before making measurements,
verify that the instrument is functioning properly, for example by testing on a known
voltage or current. Make sure that the test leads are undamaged.

Current Measurements
If tangible dangerous active parts are present in the plant where you are ma-
king measurements, individual protection equipment (e.g. suitable covers)
must be used.
Always hold the instrument below the handle shroud.
The respective accident prevention regulations established by the professional
associations are to be strictly enforced at all times regarding tasks executed
under voltage or in proximity of parts under voltage.
1) Turn selector switch (2) to the AC current range you need
2) Open the clamp, and close it round the conductor. Make sure that the clamp pro-
perly encircles the conductor, and that there is no air gap between the jaws. For
best measurement results and highest accuracy, have the conductor placed in
center of clamp jaws.
For incorrect measurement, the display equals zero. In compliance with the Kirch-
hoff's current law states the sum of all currents equals zero. However, this measu-
rement layout in conjunction with a very sensitive current clamp can be used to mea-
sure leakage currents.

If the display is not visible during measurement, press the "HOLD" button (3)
to retain the display. The clamp can then be removed from the conductor and
the stored value read.
Voltage Measurements
Do not connect more than 600 V AC / DC to the input sockets. Exceeding these
values can endanger the operator, and may result in damage to the instrument.
Before switching to a new function, disconnect the probes from the UUT.
Only handle test leads and probes on the grips provided. Avoid touching the
probes under any circumstances.
1) Turn selector switch (2) to 400V
2) Plug the black test lead into the "COM" socket and the red lead into the "VΩ"
socket
3) Connect the probes to the UUT and read the display
If the display is not visible during measurement, press the "HOLD" button (3)
to retain the display. The probes can then be removed from the conductor and
the stored value read.

Resistance Measurements / Continuity
Disconnect the UUT from all sources of supply and check that it is at zero
voltage.
1) Turn selector switch (2) to Ω/
2) Plug the black test lead into the "COM" socket and the red lead into the "+" socket
3) Connect the probes to the UUT and read the display
If the display is not visible during measurement, press the "HOLD" button (3)
to retain the display. The probes can then be removed from the conductor and
the stored value read.
Continuity: At a resistance less than 40 Ω (< 40 Ω) a signal is audible.
MIN/MAX and peak values/ Auto Power Off
The MIN/MAX button can be used to find either the largest or the smallest value of
a series of measurements. Pressing the MIN/MAX button activates first the MIN
mode, so that the smallest value is selected.
Pressing it a second time changes to MAX mode, for the largest value. Pres-
sing the button a third time returns the instrument to normal operation.

Maintenance
Provided it is used in accordance with the users manual, the instrument needs no
special maintenance.
Cleaning
If the instrument is dirty after daily usage, it is advised to clean it by using a humid
cloth and a mild household detergent.
Prior to cleaning, ensure that instrument is switched off and disconnected from
external voltage supply and any other instruments connected (such as UUT,
control instruments, etc.).
Never use acid detergents or dissolvants for cleaning.
Changing the battery
Prior to storage battery replacement, disconnect the instrument from any
circuits.
Only use batteries as described in the technical data section.
• If the symbol for Low-battery appears in the upper left corner of the display, the
battery must be changed.
This is carried out as follows:
1) Separate the Meterman Leakage Clamp AC50 from any circuit, and remove the
test leads.
2) Switch the instrument off
3) Open the housing by removing the 3 screws on the rear face.
4) Remove the old batteries
5) Insert a new batteries (type 2 x 1,5 V IEC LR6), taking care that the polarity is cor-
rect. Make sure that no wires are trapped between the 2 halves of the housing,
and close it again.
6) The instrument is now ready for further use.
Please consider your environment when you dispose of your one-way batteries or
accumulators. They belong in a rubbish dump for hazardous waste. In most cases,
the batteries can be returned to their point of sale.
Please, comply with the respective valid regulation regarding the return, recy-
cling and disposal of used batteries and accumulators.
If an instrument is not used over an extended time period, the batteries must be re-
moved. Should the instrument be contaminated by leaking battery cells, the instru-
ment has to be returned for cleaning and inspection to the factory.
9
Calibration Interval
We suggest a calibration interval of one year. If the instrument is used very often or
if it is used under rough conditions we recommend shorter intervals. If the instru-
ment is used only a few times a year, the calibration interval can be extended to 3
years.
